Release Version of Patched Firmware 72.20c for PF1 models with the 64V option ... Note: This firmware is only suitable for the 48 V models with 5kW/5kVA (PF1) and the 64 V maximum battery voltage option. It is not suitable for the older models with a PF0.8 rating (4 kW/5 kVA), nor is it suitable fo...

in this moment I have an adjusted maximal value of stretching loading, it results from observation that the inverter is charging the battery of batteries up for me up to the 75-77% of the nominal capacity, through about 5 hours of loading. I have an additional rectifier charging these batteries up t...

Hi rezydent. What is the problem you are having with your batteries? There may be a better way to fix it. What kind of batteries are they? What is the version of the main firmware in your inverter? My batteries are mine cadmium nickel with KOH electrolyte 48 cell x 150Ah 2NiOOH + Cd + 2H2O ↔ 2Ni(OH...

Hi rezydent. No, it is not possible to increase the charging voltage to 64 volts merely by a firmware change, because the capacitors, MOSFETs and IGBTs are already operating close to their rated voltages. This includes the high-voltage DC bus capacitors which have a 500 V rating and would be operat...

For me transistors broke down and I exchanged them on CSD19535KCS and IRFB3077PbF
Whether exist possibility of amending of stretching charging the battery to 64 VDC?
Do you know how it would be possible to do it?

Hi all, first please apologize for my poor english. I am runing a new solar inverter from MPP SOLAR PIP 4048 MS 5000VA DC input 48VDC AC output 230 VAC There was an error (09).The inverter has stopped working. What should I start with, check what's wrong with it ? I will be grateful for your help, ...
